Question

4.32×7.3+0.27×42.3简便计算？

Answer 1

简算如下，4.32×7.3+0.27×42.3=42.3×0.73+42.3×0.27=42.3×（0.73+0.27）=42.3×1=42.3

Answer 2

4.32*7.3+0.27*42.3

=4.32*（7.3+2.7）

=4.32*10

=43.2

Answer 3

这是典型的乘法分配律变型后进行简算的题。经过观察发现4.32和43.2存在倍数关系，我们可以把他们都变成4.32，原理就是两个因数相乘，一个因数扩大10倍，另一个因数缩小10倍，商不变。所以原来的算式可以变成：
4.32×7.3+2.7×4.32
＝4.32×（7.3+2.7）
＝4.32×10
＝43.2

Answer 4

本题简便计算过程如下：
4.32*7.3+0.27*42.3
=4.32*7.3+2.7*0.1*42.3
=4.32*7.3+2.7*4.23
=4.23*(7.3+2.7)
=4.23*10
=42.3

Answer 5

4.32x7.3十42.3x0.27＝4.32x7.3十4.32x2.7＝4.32x（7.3十2.7）＝4.32x10＝43.2
